"To tell the truth, I don't believe he recognized us," said Jack. "We were too far away for that."
"Except for the time he laid me out down the street there," said Frank ruefully. "Then the chances are he didn't take time to look at me. And he was unconscious when we came upstairs here. No, I don't believe he recognized us."
"Well, I hope we shall have the pleasure of introducing ourselves to him more fully at some future date," said Jack.
"And I have a hunch that we shall," declared Frank.
"There is nothing more to be done here," said Lord Hastings at this juncture. "We'll get back to our boat."
Accordingly they took their leave of the house, and half an hour later were again moving down the waters of the Thames.
"Where to now, sir?" asked Frank.
Lord Hastings smiled slightly.
"Can't wait until you find out, eh?" he replied. "Well, I'll tell you. We are about to do a little submarine chasing."
"Submarine chasing?" exclaimed both lads.
